The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items.
Sep 15, 2008· Iron is the most widely used of all the metals, accounting for 95% of worldwide metal production. Its low cost and high strength make it indispensable in engineering applications such as the construction of machinery and machine tools, automobiles, the hulls of large ships, and structural components for buildings.
Importance of Iron Metal. Category: Indian Geography On February 6, 2014 By Ankita Mitra. Iron is the most important among all the metals. Iron is dug out from mines. It is the most useful metals. The iron that we use is the form of iron ore. It is crushed by machines and melted in hot furnaces. Thus, pig or cast iron is made.
Other minerals, such as magnetite, contain higher concentrations of iron, but hematite is so much more abundant that it is the most economically important iron ore. In North America, over 90% of our iron comes from hematite deposits and without hematite our steel-based society could not exist.
Pure iron is a silvery-white metal that's easy to work and shape and it's just soft enough to cut through (with quite a bit of difficulty) using a knife. ... the iron ore reacts chemically with coke (a carbon-rich form of coal) and limestone. ... Blacksmiths make many important iron …
Iron is also found combined with other elements in hundreds of minerals; of greatest importance as iron ore are hematite (ferric oxide, Fe 2 O 3), magnetite (triiron tetroxide, ... In a very finely divided state metallic iron is pyrophoric (i.e., it ignites spontaneously).
The Iron Age began around 1200 BC, ending the Bronze Age that preceded it and paving the way to man’s mastery of metal. Individuals during this period began extracting iron ore to forge tools and weapons. The reason revolves around Iron being one of the most abundant metals found on earth.
Iron Ore : Important Ores of Iron Iron is the second most abundant metal after Al. It forms about 4.5% of the earth's crust. ORES OF IRON The important ores of iron are: I. Hematite, (Fe2O3) It contains about 70% iron.
The main ore minerals in bauxite are gibbsite, bohmeite, and diaspore. Antimony - The primary ore of antimony is it's sulfide, stibnite. Arsenic - Recovered from other metal processing streams (primarily from the sulfosalts such as tennantite etc.). Arsenopyrite is the most common arsenic mineral.
Hematite is the world’s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world.
A relatively common, black, metallic mineral, magnetite is also one of modern society’s most important iron ores, occurring in a variety of igneous rocks, pegmatites, contact metamorphic rocks and hydrothermal veins.
Iron ore are the rocks or minerals by which metallic iron is derived. Iron ores that carry a high quantity of hermatite or magnetite can be fed directly into blast furnaces in the iron production industry.

Iron ore is a chemical sedimentary rock that people have used as an important source of metal. The two most important minerals in these deposits are iron oxides: hematite (Fe2O3) It is the most-used metal by both tonnage and purpose.
The more active metal has to almost completely corrode before the less active iron or steel begins the process. Humans have come up with countless uses for iron, from carpentry tools and culinary equipment to complicated machinery and instruments of torture.
Jul 25, 2018· Iron ore is a chemical sedimentary rock that people have used as an important source of metal. The two most important minerals in these deposits are iron oxides: hematite (Fe2O3) It is the most-used metal by both tonnage and purpose.
Iron is the world's most commonly used metal - steel, of which iron ore is the key ingredient, representing almost 95% of all metal used per year. It is used primarily in structural engineering applications and in maritime purposes, automobiles, and general industrial applications (machinery).
An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The grade or concentration of an ore mineral, or metal, as well ...
Iron's use by humans dates back about 5000 years. It is the second most abundant metal element in the earth's crust and is primarily used to produce steel, one of the most important structural materials in the world. Pure iron is a silver-colored metal that conducts heat and electricity well. Iron ...
Iron is the most used metal in our lives. Iron is indeed an incredibly useful substance and we use it abundantly because it extremely strong than copper or wood and less brittle when compared to strong.
This hard, black substance is magnetite, an important ore of iron and a very interesting substance in its own right, which will be considered further in connection with magnetism, where its structure will be explained. The ferrous ion is greenish in solution, while the ferric ion is a light violet.
Huge concentrations occur as sedimentary iron ore; the most important source of iron: Limonite: 2Fe 2 O 3 ·3H 2 O: Earthy fracture: Brown or yellow: 1.5-4: Brownish-yellow: 3.6: Earthy masses that resemble clay.
